AT-GS950/16 and AT-GS950/24 Gigabit Ethernet Smart Switches Installation Guide

Collapsed Backbone

In the topology illustrated in Figure 5 the AT-GS950/16 is connected to other managed and unmanaged Ethernet switches to form a collapsed backbone topology. The AT-GS950/16 Switch functions as the focal point of the network by transferring Ethernet frames between the switches. This topology reduces the amount of unnecessary traffic in each workgroup, because the AT-GS950/16 Switch transfers frames only when the source and destination end nodes are located on different switches. This frees up bandwidth and improves network performance
